Help students practice and understand both place value and expanded form in three digit numbers! Included in this product are 54 expanded form trains, 6 blank expanded form trains, a recording sheet (to be printed double sided), two related expanded form worksheets, and answer keys.
Students will take one train card at a time, look at the number on the front of the train, and then “write” the expanded form of the number by selecting the correct number cards and attaching them to the train. Students may then record their answers on the provided recording sheet. Students may instead use dry erase markers to write the expanded forms of the numbers if the cards are laminated.
These expanded form train cards are meant to help students:
- practice working with three digit numbers
- understand how numbers are decomposed
- practice place value
- prepare students for mentally adding three digit numbers
Printing the pages on card stock and then laminating is highly recommended as it will increase the durability and the longevity of the product. The pieces in this product may be stored in a Ziploc bag, envelope, or plastic container.
